Abstract

Invention concernant le moulage pour vulcanisation de pneumatiques. Segment de moulage, de préférence en alliage d'aluminium, qui comporte des lamelles entourées par la coulée en un métal à point de fusion relativement élevé, en particulier en tôle d'acier; qui traverse la paroi du segment de moule, le tout de façon qu'entre les régions de lamelle entourées par la coulée et les surfaces coulées voisines il se forme des intervalles d'aération par l'intermédiaire desquels la surface intérieure et la surface extérieure du segment de moule sont reliées entre elles. Application à la fabrication des pneumatiques.Invention concerning the molding for vulcanization of tires. Casting segment, preferably of aluminum alloy, which comprises lamellae surrounded by the casting of a relatively high melting point metal, in particular of sheet steel; which passes through the wall of the mold segment, the whole in such a way that between the lamella regions surrounded by the casting and the neighboring casting surfaces there are formed ventilation gaps through which the inner surface and the outer surface of the mold segment are interconnected. Application to the manufacture of tires.
